su year, mean
forv i=`r(min)'/`r(max)'{
di in red "Now at year: " `i'
* do what you want in terms of `i'
}

Betreff: st: forval with value of variable

Dear all,

I want forval to loop over the (min) value of two variables. More
specifically, there is a variable called start_year and another called
end_year and what I want is something like this:

forval x = start_year / end_year  {
.
.
}

The variables have all the same value but i want to repeat the same
codes across different samples that have varying starting and ending
years. This is why I don't want to put the years in numbers as this
would create a lot more work.

Is there a way to do this?

Thanks.
